Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention. Example

[0017] See also Figure 1-2This embodiment provides an air-cooled power module protection frame, including a bottom plate 1, a moisture-removing layer 3, a transition layer 5 and a top plate 6. The moisture-removing layer 3 is arranged above the bottom plate 1, and an outer protective plate 2 is arranged between the moisture-removing layer 3 and the bottom plate 1 for support. The outer side of the moisture-removing layer 3 is provided with a moisture-removing filter hole 4. The outer side of the moisture-removing filter hole 4 is in contact with the air, and the inner side thereof extends to the inner position of the moisture-removing layer 3. A transition layer 5 is arranged above the moisture-removing layer 3. The transition layer 5 is a hollow shell, and a power module protection bottom bracket 8 and a limiting mold bracket 9 are arranged inside the transition layer 5. A top plate 6 is arranged above the transition layer 5.

[0018] Furthermore, the top plate 6 is provided with threaded fixing holes 101 on all four sides. The power module protection base 8 is provided with raised screws corresponding to the threaded fixing holes 101. A central positioning axis 102 is provided at the center of the top plate 6, and side positioning axes 103 are provided on the horizontal outer walls of the top plate 6. The threaded fixing holes 101 secure the top plate 6, providing protection for the power module within. Furthermore, the central and side positioning axes 102 and 103 located at the center and sides of the top plate 6 limit its position, thereby improving installation accuracy.

[0019] Furthermore, a shock-absorbing pad 201 is provided inside the outer shield 2. This pad is fixedly mounted above the base plate 1 and has multiple vertically distributed shock-absorbing springs 202 fixed to it. The upper ends of these springs are connected to the bottom of the moisture-removing layer 3. The shock-absorbing pad 201 and the shock-absorbing springs 202 can dampen the moisture-removing layer 3 above, thereby further providing a shock-absorbing function for the power module above.

[0020] Furthermore, the limiting mold tray 9 is divided into two groups, both of which are arranged on the power module protection base 8. The upper limiting mold tray 9 is provided with a fixing bolt 301 and a positioning pin 302. The fixing bolt 301 is provided at a surrounding position on the outside of the upper limiting mold tray 9, and the positioning pin 302 is provided at the center of the upper limiting mold tray 9. The upper limiting mold tray 9 is provided with a positioning groove 303 and a spare groove 304. The two groups of limiting mold trays 9 are provided with a wire management groove 305 at the center interval. The two different groups of limiting mold trays 9 can fix and limit the power module and the corresponding electrical components. At the same time, the wire management groove 305 provided in the middle position can guide and organize the connecting wires, thereby improving the efficiency of installation and subsequent maintenance.

[0021] Furthermore, a carbon-oxygen desiccant interlayer is provided inside the moisture-removing layer 3. The carbon-oxygen desiccant is a physical adsorption type desiccant with a moisture absorption rate between 50% and 70%. It can effectively remove moisture from the inside of the protective frame, thereby improving the stability of the power module during operation.

[0022] Furthermore, bottom limit knobs 7 are provided on both sides of the bottom plate 1. The staff can change the fixed position of the bottom plate 1 and the shock-absorbing pad 201 by adjusting the bottom limit knobs 7, thereby adapting to the installation state of the power module in different situations.
